Can someone give me information

Hello.. Excuse me already if my English is not great.

So I a week ago I ended up with my- solve-bit account. I received a call from a friendly guy that was going trough everything with me and he ask me to transfer 250€ for my solve bit account.

I was a little hesitated but heard some good things, and decided to go along with it. Sure enough my money was on my account straight away. (The only weird thing is, it's still not withdraw from my bank account) I use IDeal. Anyway.. I made from that week 50€ profit.. So everything is okay for right now..

Now I got a call from him just now.. If I want to invest €7,500,- for a great opportunity that is coming this way that involves bitcoin.. He was talking about the 10th of January something could take over ( I am sorry for the vage information) he was way more clear then I am right now) and I hope you guys will know what I am talking about..

My question.. Does anyone know anything about my solve bit? And if they have the best interest for the clients? Thank very much for reading my story
